The Advanced Server is an OpenVMS-based network operating system (NOS)
compatible with Microsoft networking technology. The Advanced Server
software provides a flexible system for managing wide area networks
(WANs) and local area networks (LANs). The software lets you use
Compaq Computer Corporation computers as servers to share network resources with
supported clients and is compatible with Windows NT and Windows 2000
servers running in the same network.
As a server for computers in a network, the Advanced Server provides file
and print services that enable the efficient sharing of computing
resources among a community of desktop users. It can function as a file
and print server for a small, isolated community of users or as the
foundation of a large network distributed over a wide geographical area.
You can perform Advanced Server management tasks from any client or server
that is running Windows NT server administration tools, and from any
Advanced Server using the Advanced Server ADMINISTER commands. This
document shows you how to manage your servers using Advanced Server
This overview of Advanced Server describes the role of the network
administrator, and the features available with Advanced Server, in the
- Section 1.1, The Role of the Administrator, describes what you do, as the server administrator,
and what tasks you perform to administer the network.

features, and services.
- Section 1.3, Resource Sharing, describes the resources you can share, such as
directories and print queues, and how to share them.
- Section 1.4, Monitoring Events and Troubleshooting, describes the tools you use to track resource use and
to modify your network configurations.
- Section 1.5, Network Administration Interfaces, describes the server and client software interfaces
with which you manage your servers, including the Advanced Server
ADMINISTER command-line interface.

1.1 The Role of the Administrator
When you administer any network, you plan, set up, and maintain that
network. For information on planning and design, refer to the
Compaq Advanced Server for OpenVMS Concepts and Planning Guide.
To plan a network, complete the following tasks:
- Organize the network into domains.
- Decide how to configure each server in a domain.
- Evaluate new applications and peripherals.
After planning your network and putting all hardware and connecting
links in place, you install and configure Advanced Server software. You
can then use the instructions in this document to customize and manage
1.1.1 Setting Up the Advanced Server Environment
As part of the installation, described in the Compaq Advanced Server for OpenVMS Server Installation and Configuration Guide, you specify
parameters to establish your network. After installation, you can
modify server configuration parameters in the OpenVMS Registry. For
more information, see Section 7.2, Managing Server Configuration Parameters Stored in the OpenVMS Registry.
The Advanced Server Configuration Manager allows you to modify server
parameter values, such as client capacity, OpenVMS process priority,
and network transports. For more information, see Section 7.1, Managing File Server Parameters Affecting System Resources.
Initial server configuration is performed when you install and
configure the server software. The initial configuration command
procedure, PWRK$CONFIG.COM, allows you to invoke the Configuration
Manager so you can specify server parameters during initial
configuration. The initial configuration procedure is described in the
Compaq Advanced Server for OpenVMS Server Installation and Configuration Guide. After you complete the initial installation and
configuration, you can run the Configuration Manager to modify certain
server configuration parameters, and you can modify the server
configuration parameters in the OpenVMS Registry.
1.1.2 Administering the Network
Once you have planned and set up your overall network configuration,
you support it by performing the following tasks:
- Maintaining user accounts, shares, and other resources, such as
- Monitoring events and troubleshooting server problems
18.104.22.168 Maintaining User Accounts, Shares, and Resources
Performing this maintenance includes:
- Keeping records of the network configuration
- Adding new users who need access to server resources
- Removing users who no longer need access to server resources
- Setting up and controlling shared directories
- Setting up and controlling shared print queues
- Controlling server disk storage space
- Backing up and restoring server files
22.214.171.124 Monitoring Events and Troubleshooting Server Problems
You may need to perform certain infrequently used procedures to resolve
network problems caused by unexpected conditions; for example, faulty
wiring, faulty hardware, or overloaded servers or printers.
Advanced Server provides commands and diagnostic tools to help you isolate
and fix such problems.
Chapter 6, Monitoring Events and Troubleshooting, describes some ways to monitor and troubleshoot your
1.2 The Advanced Server Network
An Advanced Server network consists of computers, both servers and
clients. Servers control resources that client systems on the network
can use. Clients are typically PC-based systems that need access to
resources on the server. Workstations and other computers running
networking software that can access network resources can be clients.
Supported client operating systems include Windows 3.11, Windows 95,
Windows 98, Windows 2000, Windows NT, Windows for Workgroups, and
MS-DOS. Compaq PATHWORKS 32 client software is supported but not
Servers in the network can run the following software:
- Advanced Server for OpenVMS, V7.2-1 (or higher)
- PATHWORKS V6 for OpenVMS (Advanced Server)
- PATHWORKS V5 for OpenVMS (LAN Manager)
- Advanced Server for UNIX (Tru64 UNIX)
- Windows NT Server V3.51 or V4
- Windows 2000
To help you manage a large and diverse network, Advanced Server software
lets you divide the network into domains, or administrative groups of
servers and clients. With domains, control of user access to the
network and its resources is centralized and simplified, and you can
establish exactly which servers a specific user can access.
A domain is a collection of computers that share a common security
database and security policy. You create a domain when you install and
configure a primary domain controller. To enable users to access
resources in domains where they have no user accounts, you can
establish trust relationships between domains. This provides
flexibility when configuring large networks with multiple domains. For
more information about planning domains, refer to the Compaq Advanced Server for OpenVMS Concepts and Planning Guide. For
more information on managing domains, see Chapter 2, Managing Domains and Servers.
Advanced Server provides two security models:
- Advanced Server Only security model
- Advanced Server and OpenVMS security model
The Advanced Server Only security model provides access based on
Advanced Server user account security policies and user access rights on
shared resources. The Advanced Server and OpenVMS security model
provides access based on both Advanced Server and OpenVMS security
policies. The Advanced Server and OpenVMS security model is never
necessary to control user access to resources, but is provided to allow
administrators of systems with complex OpenVMS security controls
already in place to use those same controls to restrict access by
client users. Note that use of the Advanced Server and OpenVMS security
model results in the extra overhead of validating both the Advanced
Server and OpenVMS settings.
A user who needs access to resources shared on a server must have
access to one of the following:
- An Advanced Server user account established on that server. A user
account contains all the information that the Advanced Server needs to
define a user, including the user name, a description, and a password.
- A server that provides Guest access to resources.
- A server that provides access based on domain trust relationships.
The user account, with its associated password, identifies the user to
the Advanced Server software. You can enable logon restrictions for each
user account; for example, limiting the hours during which the user can
access server resources.
By default, a shared resource is available to all users. You can assign
access permissions to users for resources, specifying the type of
access each user can have to a given resource. You can assign a
different set of permissions for each user and for each shared
resource. If you use the Advanced Server Only security model, access
permissions grant access to OpenVMS files and directories on the
server, regardless of the OpenVMS file protections. For more
information on the interaction of these two access permissions, see
Section 4.1.2,Advanced Server Security Models.
If a trust relationship has been established between two domains, you
can grant access to resources for users from the trusted domain. To
grant permissions to a user from a trusted domain, include the domain
name when you specify the user name. For more information on trust
relationships, see Section 2.1.8, Managing Trust Relationships.
